摘      要：With a tabletop hybrid Nd:YAG-Nd:glass laser as pump source, a compact optical parametric chirped pulse amplification (OPCPA) laser system with a peak output power of 16.7 TW and a pulse duration of 120 fs has been demonstrated. Chirped pulses are amplified from 50 pJ to more than 3.1 J with an energy gain of above 6 ×1010 by three LBO optical parametric amplifiers with a pump energy of 12.4 J at 532 nm. After compression, a final output of 2.0-J/120-fs pulse is obtained. To the best of our knowledge, it, is the highest peak output power from an OPCPA laser so far. In addition, a practical design of 1-PW laser system based on the technique of OPCPA is also proposed.
